PAPER PArL.

Specification of Letters Patent.

Patented May 26, 1908 Application filed. August 6, 1907. Serial No. 387,292.

T 0 all whom it may concern:

Be it known that I, BERTON I. BIKE, a citizen of the United States, residing at Dayton, in the county of Montgomery and State of Ohio, have invented certain new and use ful Improvements in Paper Pails; and I do declare the following to be a full, clear, and

exact description of the invention, such as will enable others skilled in the art to which it appertains to make and use the same, reference being had to the accompanying drawings, and to the letters and figures of reference marked thereon, which form a part of this specification.

This invention relates to new and useful improvements in paper pails.

The object of the invention is to provide an inexpensive paper pail having features of strength and durability which are due to the special construction of the mouth or closure flaps of the vessel. Owing to the formation of the closure of the vessel, the employment of separate fastening devices to keep the closure flaps closed is wholly unnecessary, as the closure flaps themselves have a capacity for maintaining the pail completely closed without the possibility of the closure flaps becoming accidentally opened, or opened on their own accord. And further, in addition to providing a self-closing pail, the same is also substantially slop-proof, owing to the tightness of the closure flaps and their reinforced construction. In other words, the vessel is practically liquid-tight, owing to the character of the closure flaps, and the possibility of the contents leaking from the mouth while the vessel is being carried in the hand is obviated.

Preceding a detail description of the invention, reference is made to the accompanying drawings, of which Figure 1, is a plan view of the blank showing the various score lines upon which the same is folded in completing the vessel. Fig. 2, is a perspective view of the completed vessel.

In a detail description of the invention, similar reference characters indicate corresponding parts.

The blank from which the vessel is formed is of a suitable quality ofManilla paper especially adapted for paper vessels. blank is 'cut as illustrated in the drawings, and is scored to provide two end walls 2 2 and two side walls 4 4 which are bent upright along the parallel score lines which surround The the square portion 1 of the blank at the center and which portion forms the bottom of the vessel. The end walls 2 2 have extensions 3 3 which fold inwardly on score lines and these extensions form the inner closure flaps at the mouth of the vessel when said end walls are bent upright. The side walls 4 4 also have extensions 5 and 6 folding inwardly along the score lines dividing the side walls 4 4 from the said extensions. These end extensions 5 and 6 form outer closure flaps for the mouth of the vessel and lie above the closure flaps 8 8 before referred to.

7 and 8 designate the material intervening between the end and side walls 2 2 and 4 4; these intervening portions have score lines dividing them from the end and side walls and also have diagonal score lines which enable them to overlap each other in the form of a bellows-fold, and when so overlapped to embrace the outer sides of the end walls 2 2, said overlapping folds being united to the end walls by the ends of the metallic bail' which penetrates said folds and walls and are clenched on the inner side. These outerlapping folds it will be understood enable the end and side walls to stand substantially upright from the bottom 1.

- 9 and 11 designate outer or marginal parts of the blank which join the folding portions 8 8 and the outer closure portions 5 5. These parts 9 and 11 are divided from the parts 5 and 8 by score lines and are divided or separated themselves by a diagonal score line so that the part 9 may fold against the inner side of the part 11 when the vessel is completed, and the two parts 9 and 11 so folding against each other form a reinforced top extension of the overlapping end folds 8. The score line between the portions 8 and 11 enable these end extensions to yield outwardly sufficiently in manipulating the closure flaps 5 and 6 or in closing said flaps 5 and 6 to the positions shown in Fig. 2.

It will be seen that when the vessel is folded'the portions of the blank indicated by 11 form the outer extensions of the end walls or folds 8 8, while the portions 9 lie against the inner sides of the extensions 11 and join the outer closure flaps or folds 5 5 along the score lines between these parts.

It will be observed that one of the closure flaps 56 overlaps the other and that both of said closure flaps terminate in the end extensions which join the end walls or rather the overlapping folds lying against the outer sides of the end walls and thus each closure flap or overlapping fold has a decided amount of inward pressure exerted upon its ends by these top end extensions which have the effect of staying the closure flaps or stiffening them to an extent readily appreciable. The outer one of these closure flaps 56 is turned in along the intervening score lines so that the diamond point lies beneath said flap and above the lower adjacent closure flap It will be readily appreciated that a pail constructed with a closure as described, towitconsisting of the inner closure folds 3 3 overlapping at their ends, and the outer closure flaps 56 overlapping as described, will have a maximum strength as well as a considerable amount of inherent elasticity that will-serve materially to maintain the closure flaps tight one upon the other and will thus prevent the accidental leakage of the contents of the vessel through the closure flaps. The bail 10 extends upwardly from the ends of the vessel and engages the end extensions at the point where they overlap each other, and the bail so extending exerts an additional force inwardly on the end extensions which lends additional pressure to maintain the overlapping outer closure flaps closely in contact one upon the other.

I claim:

1. A paper vessel having two opposite walls with overlapping flap extensions which form the inner closure for the mouth of the vessel, two opposite walls with overlapping flap extensions which fold transversely of the flap extensions forming the inner closure and 'which form the outer closure for the mouth of the vessel, and overlapping folds which lie against the outer sides of the two walls from which the inner closure flaps extend, said overlapping folds terminating in points which stand upright and join the ends of the flaps which form the outer closure.

2. A four-sided paper vessel, the end walls of which have cover extensions which form the inner closure for the mouth of the vessel, and the side walls of which have cover extensions folding transversely of the inner closure extensions and forming the outer closure for the mouth of the vessel, one or both of said outer closure extensions being folded upon itself to impart strength to the outer closure, and overlapping triangular folds lying against the outer sides of the end walls of the vessel, each of said triangular folds terminating in extensions which stand upright and join the ends of the cover extensions which form the outer closure of the vessel and whereby an elasticity is imparted to said outer closure extensions.

In testimony whereof I aflix my signature, in presence of two witnesses.
